EQUINOX SUN OUTAGES: Many readers reported an intermittent loss of satellite TV reception over the weekend. Was the sun to blame? Yes and no. Senior forecaster Bill Murtagh of NOAA's Space Weather Prediction Center explains: "It is likely that the sun caused the problem, but not because of solar flares. Now is the time of year for the 'equinox conjunction,' when the sun lines up with the satellite and the receiving satellite dish. When this happens, radio interference from the sun competes with signals from the satellite and can create noise levels several decibels higher than normal. The problem, which typically persists for 5 to 15 minutes, is referred to as a 'sun outage' and is often confused with sunspot or solar flare activity."
